Common misconception. Remember a "real" GTX can be overclocked further. Many
7900GTs fitted with a $30 Arctic Cooler can overclock just as well as
Gainward's GS+.
For what it's worth, the Powercolor X1950 Pro, in both PCIe and AGP forms,
has an AC Accelero X2. It, too, can overclock very well.
512 MB has shown to be of very little benefit in games, even at high-res
with AA, where the framebuffer requirements are the most demanding. The
extra RAM is probably padding up the price, but it doesn't *justify* the
price because it doesn't improve the gaming experience.
